I want to add two sub injectors. I am running a little lean at at higher psi. Looking to run no more then 20psi. what size injector recommended? Currently running 550cc. Do I need any additional equipment for my ems to run the sub injectors and can it do it? I dont want to run for 700 plus cc too much fuel to be using all the time. Thats why subs sounds a little more practical. Open to any info suggestions, Thanks

The AEM EMS will have no problem runing two more injectors, but tuning might be a challenge if your not an expert at it. Curious as to how and where you are going to mount the injectors.

I was gonna mount them into the intake pipe. You can tap it and get little bungs to weld and put the injectors in.

I am up for any other ways that might be possible if someone else has done subs on there s2k

I think 550 is a tad small for 20psi
what fuel pressure are you runnig?
check your duty cycle you prob be better off getting some larger bad boys before going sub-injectors

what size do you suggest? 720cc or bigger is just too much fuel all the time. I was told by two guys running identical set ups and similar boost actually higher then mine that i would be ok till about 18psi, but it would be close.

why would it be to much fuel all the thime if you have if tuned corrrectly.....the aem will control the pulse width of the injectors so that u will get your desired AFR.... I do not see the problem...now if yo plan to use the getto VAFC then I can see the problem....

K that is all I was checking i have the aem ems. Just wanted to know what was the best way to go. So with that answered who makes an after market fuel rail for the S? Cause I know 702cc or bigger arent fitting on that fuel rail suprised 550cc did.
